Rose's metal, Rose metal or Rose's alloy is a fusible alloy with a low melting point.
Rose's metal consists of 50% bismuth, 25–28% lead and 22–25% tin. Its melting point is between 94 °C (201 °F) and 98 °C (208 °F). The alloy does not contract on cooling.
Rose's metal has several common uses:
It was discovered by the German chemist Valentin Rose the Elder, the grandfather of Heinrich Rose.
